I agree that the fc7 version string looks strange, because
there are other things in the fc7 dmesg which are clearly from 2.6.21,
such as this:
< ACPI: Core revision 20060707
---
ACPI: Core revision 20070126
Perhaps you can try building a kernel.org 2.6.21 kernel and running
it on your FC6 install?
The ALI15X3 stuff exists only in the working FC6 dmesg:

FC7 looks like it is using libata instead:

It looks like interrupts are not being delivered?
Dunno, both 2.6.20 and 2.6.21 say they're looking on IRQ14 and IRQ15.
ACPI isn't involved at all with those IRQs, as it couldn't find any info
for 0000:00:0f.0[A] and thus the legacy hard-coding for IDE must rule the day.
Is it possible to configure 2.6.21 with the driver that was running in 2.6.20?
If yes, and that works, then we know we didn't somehow otherwise break interrupts.

These results are from the livecd from FC7-rc2, Chuck Ebbert said a new
one is soon to be released.
Let's see what the results are for this upcoming release.
Thanks,
Steve
